PROOFING-INKER.

Specification of Letters Patent.

Patented June 25, 191d.

Application filed June 8, 1917. SerialNo. 173,484.

To all whom it may concern:

Be it known that I, HORACE W. HACKER, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Proofing-Inkers, of which the following is a full, clear, concise, and exact description.

My invention relates to hand operated proofing inkers and has several objects and advantages in view. In accordance with one characteristic of the invention the inker includes a form inking roller, a frame in which said roller is mounted to turn, a handle upon the frame and at least one distributing roller and a mounting for the distributing roller that permits movement of this roller toward and from the form inking roller when the device is idle. In the preferred embodiment of the invention there are provided openings in end portions of the frame between the form inking roller and the handle in which at least one end of the shaft of the distributing roller is movable toward and from the handle and the These openings permit the distributing roller to move away from the form inking roller when the device is laid in an idle position whereby the latter roller is relieved of the pressure of the former roller when the proofing inker is at rest. The form inking rollers are usually made of impressionable composition which is likely to be injured if subjected to continued pressure of a distributing roller when the device is at rest, on which account the described arrangement of the distribut-.

ing roller is of utility.

In accordance with another characteristic of the invention the proofing inker, with or without a distributing roller or rollers, is provided with means whereby the inking roller will be maintained in an elevated position when the frame carrying it is laid upon a horizontal support, such as an inking plate with either side of the frame uppermost. By insuring the removal of the inking roller from contact with the inking plate or other support the roller will not become flattened. In conjunction with this construction there is desirably employed structural means whereby the handle may also be elevated from the support when the frame is supported with at least one and preferably either side uppermost. en the support happens to be an inking plate the handle is kept clear therefrom so as not to be spotted with ink when the device is at rest.

While the form inking roller and the handle are each preferably elevated out of contact when the device is at rest with either side of the handle frame uppermost, I do not wish to be limited to all of these characteristics.

I will explain my invention more fully by reference to the accompanying drawing showing the preferred embodiment thereof and in which Figure 1 is a side elevation of a hand operated proofing inker made in accordance with the preferred embodiment of the invention; Fig. 2 is a plan view of the structure shown in Fig. 1; Fig. 3 is a view on line 33 of Fig. 2; Fig. 4 illustrates a modification; and Fig. 5 diagrammatically indicates a characteristic of construction.

Like parts are indicated by similar characters of reference throughout the difierent figures.

The inker of my invention includes a form inking roller 1 which is usually made of impressionable resilient composition of the kind known to those familiar with the art and to which the printing ink may readily be transferred from an inking plate over which the form inking roller is passed and from which ink may readily be transferred to the form that is to be inked. This form inking roller is provided with a shaft 2 which is mounted to turn in the ends 3 of a suitable frame to which frame a handle is supplied, the handle 4: shown being in the form of a separately constructed gripping piece that is attached to the middle member 5 of the frame by means of the screw 6.

'One side of the frame carries projections 7 and 8 in the construction shown in Figs. 1 to 3 inclusive while the opposite side of the frame carries projections 9 and 10. The projections upon each side of the frame are upon opposite sides of the center of gravity of the device, such center of gravity being upon one side of the axis of rotation of the form inking roller. The said projections are upon the same side of the axis of the form inking roller with the center of gravity and the center of gravity is between the axis of the roller 1 and the, projections 8v and 10 whereas the projections 7 and 9 are between the axis of the roller 1 and the center of gravity. By this arrangement both the roller and the handle will be elethe handle, is assured. elevation out of contactftherewith to prevent it i from being spotted with ink. In 'the construction shown innFi'g. the projectionsr8' and 10 find thein'co'unterparts in the projections 8 10 that are provided upon'the-base of the handle l rather than upon theendsB of the frame as illustrated'in Figs. 1, 2 and 3. '5 I desirablyem loy two distributing rollem 11 each having a shaft 11 loosely operatingina pair-jof openings 12', 13 that are provided'in' th'e'end portions 3 of theframe upon, Opposite sides] of "the general plane occupied by the handle-and the axis of-rotationxofj'the form inkingroller. The dis tribu'tin'g rollers ar'e freely movable. toward and' from theha'ndlef and the form inking roller," such movement being permitted by said openings. Removal of the distributing rollers from the form inking roller occurs whenthe deviceis placed at rest. The distributino; rollers are desirably light-and are preferably made of wood whereby the entire structure is lightened and the form inking roller" is not unduly pressed upon thereby.

I donot'wishto be limited, however, to "the material of which aremade. L g

Atileast. one-and preferably bothopenin'gs" 12,13 of each pair has, in the constructionof Figs. 1', 3' and- 5', two sidesl l, 15 generally oblique to'the general plane occupied by the' handle and the aXis of rotation of the form'inking' roller, one side extend-i in-g toward-said planeaway from the form I inking'roller and "the other; side away from terna'l sides of' said openings" are substantia-lly parallel"withftheaforesaid plane but 3 I prefer the construction illustrated inHFigsQ;v 1, 3 and"5":" The openings are preferably' triangular'in. shape but I donot wish t9 be said plane and "also fromsaid form inking roller.lj.,By thisconstruction of said-openings'the' distributing rollers fall away from the form inking rollerlwhen the device is atrest whereby 'the'weightof the distributing rollers then'relieved from the form inking" roller topreventthef "form inking roua'arbm becoming impaired while the device is idle.
